Original application filed .Tune 2, 1909, Serial No. 499,797. Divided and. this application filed November 30, 1909. Serial No. 530,655.

To all whom it may concern:

Be. it known that I, DAVID PEI/ION Moonn, a citizen of the United States, residing at Washington, in the District of Columbia,

have invented certain new and useful Imafiixing machines, this application being a divisional ap lication of my application filed June 2n 1909, Serial No. 499,797, for

- the complete tag forming and aflixing machine.

The cutting mechanism must be simple, durable and inexpensive, and toward this end, I have provided a stationary blade mounted in the pivoted casing of the mav chine and through which the tape to be cut is fed, so that upon the downward movement of the casin upon the anvil, a slidingly mounted knife co-acts with the stationary blade to shear or cut-off the predetermined length of ta e to form the tag,

which is thus deposite upon the article to receive the ta said article having been pre viously place upon the anvil.

In mounting the sliding knife, I employ an adjustable and practically self-sharpenmost position.

ing device, and rovide a mechanism, which is also adjustab e, which as the casing is moved away from the anvil returns the slidable knife to allow the tape to be fed through the stationary blade, and which as the casing is moved toward the anvil is operated to cut the tape and form the tag.

To clearly understand the cutting mechanism, attention is invited to the accompanying drawings, in which Figure 1 is a front elevation of the cutting mechanism in the osition it assumes when thecasin which is in dotted lines, is up, the base so being indotted lines. Ei 2 IS a similar view, the cutting mechanism ing at its. lowermost cutting position. Fig; 3

is a lon 'tudinal- .sectionthrough the forward on of the casing and showing a portion of the base. vFig. 4 is an enlargeddetail view of the stationary blade and the sliding blade, the sliding blade being its upper Referring to the drawings :--The numeral 1 designates the base of the machine, u on which is mounted the stationary anv' whichin turn is provided with the stapleclenching means or recesses 3, while pivoted to the base and in line with the anvil and so as to swing in an arc of a circle with the pivot as a center, is the pivoted casing 5, whose outer end 4, is adapted,'when the easing is in its lowermost position, to rest upon the top of the anvil. Carried by this casing are the two tape feeding rollers 6, which feed the tape forwardly upon the upwardmovement of the casing through the horizontal slot 7, of the stationary knife or blade 8, which is secured removably to the outer lower face of the casing, and is pro vided with the lower rounded surface 9, which will. not injure the article to be tagged, when the casing is brought down u on the article and anvil. Just forward 0 the outer face of the stationary knife or blade 8, is the vertical knife guiding and receiving slot 10, into which from the upper end is inserted the vertically reciprocating or sliding knife blade 11, whose cutting ed e 12, is formed at an an le so that as the kni e blade 11 descends in front of the stationary blade 8, a shear cut is given the tape, thus forming a tag and del vering it upon the article upon the anvil. To operate this knife blade 11, I employ the rod or beam 13,Wh0se inner end is pivotall secured centrally of the rear face of the b ade 11, while the center of the rod or beam 13, is pivoted to the rear of the casing as at 14, the outer end 15 of the beam 13, being pivotally secured to the adjustable actuating rod 16, whose lower end is threaded and carries the :upper and lower adjusting nuts 17 and 18, respectively. This threaded end of the rod 16 passes through an opening in the base, so that the nut 17 is above the base, while the nut 18 is below the base, and in order to cause the knife blade 11 to be operated at theproper time, these nuts are adjusted upon the rod. By this means'it will be seen that as the casing is moved away from the anvil, the rod 16 pulls downwardly upon the beam 13, raising the knife blade 11, and as the casing descends or moves toward the anvil, the knife blade 11 is caused to descend and cut the tape projected through the slotof the j J stationary blade 8.

knife blade 11, the .knife blade passes upwardly in front of the Stationary blade 8.

just prior to the projection of the tape through the slot of the blade 8, thus preventing any stoppage of the machine.

In order to hold the knife blade 11 properly against the outer face of the stationary blade 8, as it ascends and descends, I employ the two balls 19, which are mounted in the channels 20 of the block 21, and are provided with springs 22, and adjusting screws 23, whereby the balls are given a spring tension, so that as these springs are com pressed the balls recede within the chan-- nels, where, as the knifeblade 11 descends and ascends, said balls ride upon and press 7 the knife toward the stationary blade 8, this action upon the ascending of the knife blade 11, forming a self-sharpening means, as the inner'faoe of the cutting edge of the'knife blade 11 is given a whetting action against the outer face of the stationary blade 8. I have found by tests, that this combination automatically sharpens the blade 11, the action produced being the same as when shears are opened with a tension against the blades. Upon the outer face of the-knife is carried the right-angled inverted L-shaped lug 24, which permits the stapling device bar 25 to ascend, only far enough when the casing is up, to prevent its plungers from cutting and delivering the staples.

What I claim, as new, is 1. In a tag forming and afiixin machine, the combination with a base, and an anvil carried thereby, of a casing mounted upon the base and capable of movements toward j and away from the anvil, tape feeding means -i adapted to feed the tape upon the movejment of the casing away from the anvil, a llknife slidably mounted in the casing beyond tithe feeding means, and means for operating 'ithe knife to sever the feed tape as the cas- Fing is moved toward the anvil, and return the knife when moved away from the anvil. 2. In a tag forming and afiixin machine,

the combination with a base, an an anvil carried thereby, of a casing mounted upon the base and capable of movements toward and away from the anvil, tape feeding means, a stationary blade mounted in the casing for iding the tape toward the anvil, a knife b ade vertically reciprocatory in front of the stationary blade and adapted to co-act with said stationary blade to sever the tape as the casing moves toward .the anvil, and means for operating the reciprocatory blade, the movement of the casing away from the anvil returning the reciprocatory blade to inoperative position while the movement toward the anvil causes the blade to co-act with the stationary blade to sever the tape. v v 3. In a tag forming and aflixing machine, the combination with a' base and an anvil carried thereby, of a casing mounted upon the base and capable ofmovementstoward and away from the anvil, tape feeding means, a'stationary blade mounted in the casing for guiding the tape toward the anvil, a 'knife'blade vertically reciprocatory in the casing and adapted to co-act with the sta tionary blade to severthe tape, adjustable means for holdin the knife blade toward the stationary bla e, and means for operating the reciprocatory blade, the movement of the casing away from the anvil returning the blade to inoperative position while the movement of the casing toward the anvil causes the blade to co-act with the stationary blade to sever the tape.

'4.
